PDF saver

Have you noticed that Pocket doesn't really grok PDFs? Thankfully a lazy dev with no actual knowledge of javascript is here to help! Enter "PDF saver": now with a click of a button your PDF filled to a brim with sweet sweet metadata (title & tags) goes straight to Pocket.
*Updated so your favourite PDFs from arXiv to Pocket will have a correct title even if there is an empty title field in the PDF itself!
